Introduction1
1.1General
The Lumio Integrator guide provides technical guidelines for integration of Lumio Touch Screen panels into LCD
and Plasma monitors.
Integrate Touch Screen panels into Monitors only after an Integration Design is prepared and
approved by the Integrators’ engineers, according to Lumio Integration Design requirements and
recommendations (see the Lumio Design guide for Integrators), and any other requirements that
Integrators and their Engineers deem necessary. Lumio is neither responsible for integration designs
nor their implementation!
1.2References
The following references are mentioned in this guide:
•Lumio Design Guide for Integrators
•Lumio Crystal Touch Manager User guide
1.3Safety Instructions and Precautions
Comply with the following safety instructions and precautions regarding handling and usage of Lumio Touch
Screen panels, in order to prevent harm and damage to the various system components, and to ensure
successful integration.
•Only qualified integrators are authorized to integrate Touch Screens into monitors
•Do not integrate Touch Screens without an approved engineer integrator design plan
•Do not integrate or service Touch Screensbefore reading all safety and operation instructions
•Connect electrical components to a power supply that is properly grounded
•During integration or maintenance, disconnect the Touch Screen from the electrical supply
•Do not perform any electrical, mechanical or other changes to Touch Screen and their components without prior
written Lumio authorization
•Handle Touch Screen panels with care - they are glass
•Do not subject Touch Screen panels to unnecessary shock or stress
•Do not lift a Touch Screen panel by the Active Barrier or by its flat cables
•Large Touch Screen panels are heavy, and should be carried by at least two people
•Do not stack Touch Screen panels on top of each other
•Do not place heavy objects on the Touch Screen panels
•Ensure Touch Screen storage temperature as specified in the Lumio Design guide for Integrators
•Ensure that the monitor is well ventilated. The Touch Screen temperature should not exceed the value displayed in
the Integrator Design guide
•Wear gloves when handling Touch Screens to prevent unnecessary fingerprints on the panel
•Clean Touch Screens with a dry cloth or with a soft cloth soaked in neutral detergent (after wringing dry)
•Do not use any organic solvents, acids or alkali solutions to clean glass Touch Screens (for further cleaning
instructions, see Cleaning on page 9)

System Overview2
The Lumio Touch Screen is a pre-calibrated plug and play optical Touch Screen that is integrated into various
environments according to customer needs. Successful integration is dependent on the implementation of the
requirements specified in this guide.
The following block diagrams display the Touch Screen environment and Touch Screen components:
•Touch Screen Environment Block Diagram below
•Touch Screen Environment with Detailed Active Barrier Block Diagram on page 6
2.1Touch Screen Environment Block Diagram
The following diagram displays the Touch Screen environment.
Figure 1: Touch Screen Environment
2.1.1 Touch Screen Environment Components
The Touch Screen environment includes the following components:
Table 1: Touch Screen Environment Components
A The Illumination Control Signal, supplied by the Crystal Touch PCB Controller (PCB Controller) to the Touch Screen
panel. The Illumination Control Signal turns the Touch Screen’s Active Barrier on and off
B Light obstructions caused by the User fingers / objects
C The IR (Infra-Red) illumination generated by the Active Barrier. The IR light is transmitted to the sensors. The light
wavelength is 830nm±20nm
D The mechanical connections between:
•The Touch Screen and the Host’s monitor / screen
•The Touch Screen and the Host screen's bezel
E Touch events transmitted by the PCB Controller to the Host via USB-HID. Supported interfaces include HID-mouse,
HID-digitizer, HID-pointer / mouse
F The Analog Data Sensor. The signal sample rate is 500 KHz
G The settings information and calibration data exchange between the Crystal Touch Manager application, and the PCB
Controller
H The USB settings commands exchanged between the manufacturing tool software and the PCB Controller

2.2Touch Screen Environment with Detailed Active Barrier
Block Diagram
The following diagram displays the detailed Active Barrier’s components in the Touch Screen environment.
Figure 2: Detailed Active Barrier in Touch Screen Environment
2.2.1 Active Barrier Components
The Active Barrier environment includes the following components:
Table 2: Active Barrier Components
Glass: The glass is the substrate or surface for all optical components
Sensor Module Sensor Module: The Sensor is a module featuring, high accuracy, high resolution and high
sensitivity. Each system includes four optical Sensors placed on the corners of the panel (In two
sensor systems, the sensors are placed on the top corners of the panel). These Sensors are
assembled on the glass
Rod The Rod is an optical element that distributes the light uniformly. The Rod is inserted into the Rod
Holder
Rod Holder The Rod Holder encases the Rod and protects the Rod from humidity, dust and particles. It is
assembled on the glass
Led Wire The LED Wire is a cable that connects all IR LEDs mounted on their PCBs (LED PCBs). The wire is
connected to the PCB Controller. The number of LED PCBs depends on screen size and screen type

Work Flow3
The following flowchart displays an overall view of the work flow and procedures required to integrate the
Touch Screens into monitors.

IQC: Incoming Quality Control Inspection4
Comply with the following Incoming Quality Control (IQC) inspection and acceptance requirements prior to
Touch Screen integration.
•Incoming Touch Screen Kit Content Inspection below
•Visual Inspection below
•Incoming Touch Screen Glass Panel Inspection on page 9
•Functional Inspection on page 13
4.1Incoming Touch Screen Kit Content Inspection
Ensure that the Touch Screen components received comply with the Touch Screen Kit Content supplied by
Lumio as part of the shipping documents.
4.2Visual Inspection
Visually inspect the following components.
Table 4 Kit Components
Component
Inspection
Touch Screen Panel
Verify that:
•The Sensors are attached to the Touch Screen panel
•Each Sensors is attached to an FFC cable
•The Rod Holders are attached to the Touch Screen panel
•The glass panel is not broken
PCB Controller
•Verify that the connectors on the PCB Controller are intact
•Verify that the connector lockers on the PCB (for the FFC cables) are not broken or
missing
•Ensure that each FFC cable is connected to the correct sensor connector on the PCB
Controller
Flat Cables (FFC)
•Ensure that the flat cables are intact and include a blue ribbon at their end
•Ensure that each cable is connected to the PCB Controller at one end, and to a sensor at
the other end
LED Wires
Verify that the LED wire is connected to the PCB Controller (JP3 on the board) via a LED
extension power cable

Touch Screen glass panel inspection includes the following:
•Inspection Requirements below
•General below
•Mechanical Criteria on page 10
4.3.1 Inspection Requirements
Ensure that the following conditions apply prior to and during the Touch Screen inspection.

•For Touch Screen between 26” - 52”: 15 ÷ 25 sec
•For Touch Screen sizes larger than 52”: 20 ÷ 30 sec
Note: Only Touch Screen anomalies detected during inspection under the above conditions constitute grounds for rejecting
the Touch Screen.
4.3.2 General
The following general Touch Screen glass panel requirements apply:
•Prior to inspection, clean the glass and ensure that finger prints and other foreign materials are removed

the monitor. Prior to mounting, clean the Touch Screen glass panel, removing marks, finger prints, dust and any
foreign object or contamination.
4.3.3 Cleaning
The following Touch Screen glass cleaning requirements apply:
•Clean the glass before and after each activity during the integrating process
•Clean the glass Touch Screen with clean cloth and windows dedicated liquid only
•Use only alcohol based solvents to dissolve oily contaminations and marks
•Do not use acid based solvents such as WD-40 or acetone
•For further cleaning requirements, see Appendix D: Cleaning Materials on page 41
